          com.sencha.gxt.chart.client.chart.series.LineSeries<M>

Type Parameters:

M - the data type used by the series

All Implemented Interfaces:

SeriesHandler.HasSeriesHandlers, SeriesItemOutEvent.HasSeriesItemOutHandlers, SeriesItemOverEvent.HasSeriesItemOverHandlers, SeriesSelectionEvent.HasSeriesSelectionHandlers
